Vauxhall Insignia Grand Sport (2017-2021) Pros and Cons

Pros	Cons
Keenly priced on the used market	Not at all sporty to drive
Economical diesels ideal for motorway driving	The Country Tourer isn't necessarily four-wheel drive
Well equipped whichever model you choose	A Skoda Superb is much more spacious

Quick Summary

The Vauxhall Insignia Grand Sport (2017-2021) is a D-segment saloon that competes with the Ford Mondeo and Volkswagen Passat. Despite its saloon appearance, it's actually a five-door hatchback with a full-opening tailgate. Available in three body styles—Grand Sport hatchback, Sports Tourer estate, and Country Tourer with extra cladding—it was primarily aimed at the company car market. The range offers extensive engine options, from a 1.6-litre diesel with 109bhp to a 207bhp twin-turbo diesel in the GSi model, with several petrol alternatives in between. The 1.5-litre petrol with 163bhp offers the best balance of performance, torque, and fuel economy.

Practicality is a strong suit, with a 490-litre boot expanding to 1,450 litres with rear seats folded, plus optional 40:20:40 split-folding rear seats. Running costs are reasonable, with efficient diesels achieving around 55mpg and the 1.5-litre petrol closer to 45mpg. Most models feature timing chains, reducing maintenance costs, though 2.0-litre diesels require timing belt changes every six years or 100,000 miles. As a used purchase, the Insignia Grand Sport represents excellent value with abundant availability and significant depreciation benefits. However, it prioritises comfort and practicality over sporty driving dynamics, and the Skoda Superb offers superior space in this class.

Best for: Budget-conscious buyers seeking a spacious, well-equipped family saloon or estate; company car users; those prioritising motorway comfort and diesel efficiency.

Not ideal for: Drivers seeking sporty handling or premium badge appeal; buyers wanting maximum boot space; those requiring four-wheel drive as standard on all models.


Comparison vs Key Rivals



The Verdict

You should buy the Insignia Grand Sport if: You're seeking a spacious, well-equipped family saloon or estate on a budget, prioritising motorway comfort and diesel efficiency, or looking for excellent used value with abundant availability.

Consider alternatives if: You want sporty handling, premium badge appeal, maximum boot space, or require four-wheel drive as standard on all models.

Competitive Position: The Vauxhall Insignia Grand Sport is a solid, sensible, and dependable family choice offering excellent value and generous equipment levels. Whilst it won't excite with class or sporty driving dynamics, its affordability, practicality, and low running costs make it a worthy contender against the Ford Mondeo and Volkswagen Passat. However, the Skoda Superb remains its biggest rival, offering superior space and higher user ratings, whilst the Peugeot 508 provides more premium appeal. For budget-conscious buyers prioritising practicality over performance, the Insignia Grand Sport represents outstanding second-hand value with abundant stock and significant depreciation benefits.
